Abstract

: In this paper an algorithm is developed to predict the maximum and minimum inductance of an optimized pole arc of a fabricated double salient reluctance machine (DSRM). The developed analytical algorithm investigates the air gap length at the maximum and minimum inductances. These are achieved through the machine rotor pole arc, stator pole arc, bore diameter, back iron thickness, rotor yoke thickness, stack length, and rotor pole diameter. The validity of the newly developed analytical procedures for predicting the maximum and minimum inductances was evaluated using the measurements obtained from the machine prototype. There was a good correlation between the analytical and experimental results. Inductances and air gap lengths of 2/2 DSRM of equal stator and rotor pole width and stator pole width greater than the rotor pole width were investigated and analyzed using the developed algorithm. A second existing DSRM with different numbers of stator and rotor poles whose inductances have been known and compared with finite element analysis (FEA) is chosen to verify the algorithm developed. The 2/2 DSRM’s potential to sustain oscillation during energy conversion from mechanical energy to electrical energy is investigated.

双凸极磁阻电机(DSRM)气隙长度和最大、最小电感的分析算法

本文提出了一种预测双凸极磁阻电机优化极弧电感最大值和最小值的算法。所开发的解析算法研究了最大和最小电感时的气隙长度。这些是通过电机转子极弧、定子极弧、内径、背铁厚度、转子轭厚、堆长和转子极直径来实现的。利用从机器样机中获得的测量结果，评估了新开发的预测最大和最小电感的分析方法的有效性。分析结果与实验结果有很好的相关性。利用所开发的算法对定子与转子极宽相等和定子极宽大于转子极宽的2/2 DSRM的电感和气隙长度进行了研究和分析。选取了已知定子和转子极数不同且电感值已知的第二种现有DSRM，并与有限元分析(FEA)进行了比较，验证了所开发的算法。研究了2/2 DSRM在从机械能到电能转换过程中维持振荡的潜力。
